2 Claims.

This invention relates to a combined plaster ground and door trim to be used around wall openings, such as doors and windows in buildings. There are many advantages to be derived from the invention including the extreme simplicity of manufacture; the ease and rapidity of installation; the automatic securing of a closed joint between the strip embodying the ground and the door or window frame; and in the neat appearance as well as the presentation of a limited surface to be painted or otherwise finished.

These and many other objects and advantages will become apparent to those versed in the art in the following description of one particular form of the invention which is made in reference to the accompanying drawing in which Fig. 1 is a view'in perspective of a length of moulding embodying the invention;

Fig. 2, a view in side elevation of a fragmentary portion of the wall and frame to which the invention is applied, and

Fig. 3, a view in transverse section on the line 33 in Fig. 2.

Like characters of reference indicate like parts in the several views in the drawing.

The moulding generally designated by the: numeral it is formed in desired lengths to have a planar foot H from which is outwardly turned a leg i2 also planar, this leg l2 being at right angles to the foot 1 i. From the outer portion of the leg ii the material is bent around by a short bend it back and inwardly on the outside of the leg 52, Fig. 3, for a short distance which does not exceed to any great extent the thickness of the usual skim or white coat of the plaster.

Then from a line It defining the inward projection of the loop 53 on the outside of the leg l2, the material is carried laterally outwardly and then around in a continuous curving portion IE to terminate by an end l6 which is spaced back or below the under side of the foot II a distance approximately around 1%; of an inch, this dimension being variable but sufiicient to accomplish the desired purpose. In other words the arcuate portion I joins the outer portion of the leg l2, not directly, but only through the bend l 3 which projects outwardly therefrom to serve as the actual edge over which the plaster is leveled by the usual float or other like tool. In reference to the extension of the bend l3 from the line I4, I

this of course may be varied but it is desirable to keep it at a minimum dimension such as around T15 of an inch.

Defining the opening in a wall is the usual stud 11 against which a door or window frame member I8 is secured either in direct contact as illustrated in the accompanying drawing, or separated therefrom by shims all in the usual and well known manner to those versed in the art. In any event the frame member I8 is provided with a slot is extending longitudinally therealong, and importantly, having its side walls inclined outwardly from the entrance side 23 in respect to the back face 2! of the member i8, Fig. 3. The length of the moulding I9 is applied by inserting the end It into the slot is and bringing the foot H up flatly against the stud IT as indicated in Fig. 3. The foot H is provided with a plurality of holes 22 therethrough to receive nails or the like 23 therethrough as they may be driven into the stud [1. It may be desir able also to supply holes 24 through the junction of the foot II with the leg [2 whereby nails 25 may be driven diagonally through th moulding and into the stud i l, or primarily into the frame member l8 as indicated in order to fit the leg I! snugly and compressibly against the stud ii.

Further the formation of the moulding I0 is such that when the foot II is brought into full contact with the stud ll, the end portion of the moulding Ii] terminating in the end it is forced around into compressive contact with the outer corner 2% of the slot 19. This contact is initially made and maintained by reason of the curvature of the moulding part I 5 which causes the edge It to slide down the inner wall 2! of the slot 19 then to straighten slightly the portion l5 and thereby urge the outward convex surface against that corner 26.

Then in the usual manner, plaster board or lath 23 is nailed by an edge portion to the stud ll such as by the nails 29, and the plaster til is applied thereover and leveled over the bend it with the skim cut 3| applied thereafter. Generally the thickness of the board 2& is and the plaster 36 is of the same thickness to equal the overall dimension of the leg l2 from the foot H to the outside of the bend it to be sub-stantially of an inch. The moulding It! is provided with clinch holes 32 through the leg l2 whereby the plaster may flow therethrough when it is applied and clinched over the leg l2 behind the portion [5. The concave portion it may be painted or otherwise finished as may be desired to give a very neat as well as a protective surface around the edge of the plaster, between it and the frame member it.

While I have herein shown and described the invention in the one particular form, it is obvious that structural changes may be employed without departing from the spirit of the invention and I therefore do not desire to be limited to that precise form beyond the limitations which be imposed by the following claims.

I claim:

1. The combination with two juxtaposed wall structure members wherein a surface of each is approximately in a common plane, of a trim molding bridging said members; one of said members having a slot entering its said surface to extend longitudinally thereof said slot being defined by spaced apart, substantially parallel walls inclined from said one member surface sloping therefrom within the member away from said second member, the slot wall farthest removed from said second member forming an acute angled corner between it and said surface; said trim molding having a foot bearing over said second member surface, and having an arcuate portion carried by said foot and extending laterally therefrom; said arcuate portion having .an outwardly convexly curved length terminating in a free edge spaced laterally from said foot a distance bridging said two members between said edge and said foot; said edge being spaced back of said foot a distance entering within said slot below said one member surface with said foot bearing over said second member; the transverse width and the inclination of the walls of said slot and the curvature of said arcuate portion having that relationship wherein said curved length bears substantially by a line contact along said corner compressively urged thereagainst by said edge bearing compressively against the opposite slot wall from said corner.

2. The combination with two juxtaposed wall structure members wherein a surface of each is approximately in a common plane, of a trim molding bridging said members; one of said members having a slot entering its said surface to extend longitudinally thereof; said slot being defined by spaced apart, substantially parallel walls inclined from said one member surface sloping therefrom within the member away from said second member, the slot wall farthest removed from said second member forming an acute angled corner between it and said surface; said trim molding having a foot bearing over said second member surface, and having an arcuate portion carried by said foot and extending laterally therefrom; said arcuate portion having an outwardly convexly curved length terminating in a free edge spaced laterally from said foot a distance bridging said two members between said edge and said foot; said edge being spaced back of'sa'id foot a distance entering within said slot below said one member surface with said foot bearing over said second member; the relationship of the transverse width, the inclination of the walls of said slot, and the curvature of said arcuate portion having said curved length of the arcuate portion bearing substantially by a line contact spaced from said edge and along said corner under a straightening bending stress induced by said edge bearing compressively against the opposite slot wall from said corner substantially by a line contact, the contact line being spaced inwardly of the slot from said one member surface.
